To all 107mm it'mag concern: g

Be it known that I, Cnamaxcn S. JOHN- s'rox, a citizen of .the UnitedStates. residing at Glendive, in the county of Dawson and State ofMontana, have invented a new and useful Demountable Rim, of which thefollowing is a specification.

it is the obge'ct of th s invention to pro- 1 v VldQ novel means wherebya demountable rim maybe held upon a wheel body.

' It, is within the province of the disclosure to improve generally andto enhance the'utility of devices of that type to which .the presentinvention appertain's.

llith the above and other ob eets 111F183- which will appear as thedescription pro-. ceeds, the invention resides in the combma-- tion' andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it'being understood thatrhangcs in the preciseembodiment of the inventionherein disclosed can be made within the scopeof what is claimed without departing from'the spirit of the invention.

"ture shown in Fig. 1:-

In the accompanying drawings Figure l is a side elevation, sh'owm a partI of a wheel equipped with the device orming the subject matter of thisapplication;

Fig. 2 is a transverse scction'of the struc- Fig. 3 is a topplan of thet'ell v'band. portions of the rim appearing in section; and

Fig; .4 is a fragmental longitudinal sec'-,.

lion showing a p rtion of the rim.

in the drawings there IS. shown a wheel body comprising a fell; 1circumscribed by afelly band 2 provnlwi'at oneslde with a flange 3. Thetelly bandQ'i-s supplied with outwardly extended radiai projections 4,portions of the inner edges of which arein clincd as shown at 5. fi rim6 is adapted to be slid transversely of the telly band 2 and is providedwith any suitable means indicated at. 7 for retaining a tire S; The'i'elly band 2 and the telly 1 are supplied with .eli'mgaled openings 1%in which the valve stem (not shown) of the tire 8 isadapted to more whenrelative circumferential moveincnl takes place between the telly band 2and the rim 6. The rim 6 may be divided .as shown at 9, and any suitablelatch means 10 may be provided forholdin'g the ends of the rimdctachably together. able means may be provided for connecting the endsof the rim 6, and since a latch meeh-- anism of any kind is a separateinvention lhercin.

Since any suit-.

from the one' hercin claimed, the latch means need not be described indetail.
